' TOOL-HOLDER To all whom it may concern: I

B'e it known that I, GEORGE W. HENRY, a citizen of the United States,residing"at Ridgewood Heights, borough of Queens,

city of New York, in the county of Queens and State of New York,;haveinvented certain new and useful Improvements in Tool- Holders, of whichthe following is a specification.

mentioned, which is simple in construction, strong and durable, isserviceable to hold tools projecting fromthe end of the tool holder aswell as. various constructions .of. tools projecting laterally from thetool holder. and tools mounted upon a transverse pin or support held inthe tool holder.

In" the accompanying drawings in, WhlCh' like letters of referenceindicate like parts in all the figures z Figure lis a side view ofoneembodiment of my improved toolrholder. I

Fig. 11 is a plan view of the holding clamp for the parting tool orother cutting tool, shownin Figs. 8,9 and 10.

The tool holder is composed of-fa shank 1 made in theshape of a shank ofa tool such as iscommonly used in lathes, planers, and I so forth. Atoneend this shank is provided with, a head portion 2. made integral withthe shankand which shank and head can be straight as shown in Figs. 5, 8and 9, or

can be offset as shown in Fig.1. The bottom edge. of the tool holder andthe head; P F fi Pre ra ly: orm 0 -1 9, .t .-1 s

straight line as indicated at 3.-in Figs. 1 and 3.' Ahole for a cutter 4extends from the end ofthe head to the side of the shank and is inclineddownward as shown,so that anordinary lathe tool5 which is placed intoSpecification of Letters Batent. i Patented Dec. 3, 1918. i

this hole for a cutter, projects from the end, surface of the headupward at an inclinationl The hole for a cutter 4 is intersect ed-by asecond hole for a cutter 6', which extends through the head 2 from oneside surface.to nanotherwand intersects the hole for a cutter l in thebottom surface of the ;same, as indicated at 7, so that the tool or partofa. tool can be placedinto said trans,

verse hole for a cutter 6 and held transverselyxto the tool 'holder, forexample a tool 9 of Fig.,.5. or the tool supports 10" and 11 of Figs.and 7,:which will bedescribed later.

.The holefor a cutter 4 terminates in a re- 1 cess l2 initheupper partof theen'd'surface of the head, {so that this recess communiv cates withlthe longitudinal hole, for a cutter 4 and the transverse. hole for. acutter 6. A screw, threadedihole 13 extends downward fro1n,.,the topedge of thehead 2 to the top of the holefor a cutter 4 and in thisthreaded hole there is mounted a screw The screw 14 14 for clamping theparts. has a polygonalhead 15 for applying a'key, and directly. belowthe head is provided with a bearing shoulder 16. A clamp'17is providedwith a downwardly projecting jaw 1' 18 at'jone end, which jaw can passthrough the recess 12 V, and into the transverse hole fora cutter 6iandis in front of the partition 19 formedbetween thebottom of the recessThe undersideof-the body ofthe clamp 17 is finished off straight, asshown .at20, and at the inner endof a straight portion 21 on the top 1of the head a shoulder 22 is formed, so

.that whenthe clamp is placed on the ,top of the head, with. its lug,inthe recess 12 and the end ofthe lug in the transverse hole forjacutter 6, the end edge 23'ofthe clamp rests against the shoulder 22.which forms an abutment. The clamp is raised from the top of the head,except at its end 23, bythev jaw '18, engaging the tool and the pressureof the jaw on the tool is produced by the shoulder 16 on the. screw.

Theclamp'is provided with a smooth hole 24 extending from top to bottomand of sufi ioient sizefor thescrew 14 to pass freely through the same.If the tool 5' is inserted. in the tool holder sofas. to PI'OJBCE fromthe end of the head athe main portion ozfiSaid" tool rests within thehole for a cutter 4. and is clamped in the same by means of the clamp,the lug 18'of which ispresse'd on the upper surface of'said tool by thescrew 14 which is drawn up tight. The tool 5 can be adjusted inward andoutward to project a greater or less distance and a tool can be firmly{and securely held if it is only of sufiicient length to pass intothehol'e. for a in Fig. 9 and in such cases the tool holder cutter asfar as the lug or jaw '18 of the clamp and thus the smallest pieces: oftool steel can'be used, for example as short as one inch.

' If the tool is of gre'ater lengthfitsbit end can' 'project from theend of the tool holder as shown in dotted lines. in Fig.1, and the innerend can project from the end of the hole for a'cutter 45 and beyond thesides of the'shank, at'an inclination. When the tool holder ismadestraight and without an ofi'set, the hole for a cutter 4 extends to' theunderside of the tool holder," as shown can project from. the. undersidevoiiii slie shank:

I When the tool ism be held laterally to the tool holder, the transversehole for a cutter 6 is used and the tool is adjusted in the same toproject a greater orless distance beyond one side'face of the head, andthe tool is then clamped by means of the'jaw-' 18,jwhich engages thetoo1, -whi1ch n1a'y be square, polygonal,or round in cross section.Theclamp ispressed' down by means of the screw ltfi-n.

the manner previously described. -For the purpose of holding a knurl orothertools, a

tool support 10 is placed into the transverse hole for a cutter'6 andheld by means of the clamp in the manner above vdescribed,

1 the-said supportbeing preferably. provided witharecess-QG, into whichthe lug or jaw 18' of the clamp engages. This stud can'be provided withDecks 2'? on itsends, onwhich necks the gkn'url holder 28 for thelfmurl29 is fastenedby means of .a screw '30. A f thread cutting tool orany'other cutting tool 31 may be mounted on aineck of a tool'support 11,as shown in Fig; '1'.

To prevent this cutter'f'rom turning and also-tobring'it to the properangle, a block 32 having a square hole for receiving the squared part ofthe support 11',- is Tfirst slipped on the support 11 and a screw 33mounted in the block 32 bears upon the edge oi the cutter 31 so as tokeep it from turning around, and at the proper angle. t

For the purpose of holding a partingtool or other cuttingtool, the headof the shank is provided with a bottom .fla g 35: whi h projectslaterally; the top or which flange forms an inwardly tapered or inclined$110111- deliv 361-. A cutter or partjng teal; ssrests onthis shoulder36 and "itsiipper edge "39 is, clamping bloclr 7 4:0 which is passedthrough the .transverse hole for a cutter The clamping block 40 isprovided "at one end with alug 41 which projects beyond said end, at thetop of the tool, and has its bottom edge beveled so astoengage theupper-edge of the cutter 38. Theclainp;

ing block 40 is providedin' its upper surface with a'rec'ess 42 whichcan beentered by the jaw 180i the clamp 17.

Having described my invention what. I- V claim as new and desire tosecure by Letters Patent is'z 1'. A tool holder consisting of ashanleterminating in ahead and havinga hole for a cutterextending lengthwisethrough the head portion and a hole for a cutter-extend,
